Can anyone tell me if a Miller Maxstar 150 STL is worth fixing?
I don’t know what’s wrong with it. All I want is a 110v stick welder and I’m sure I could get this Miller cheap
i have seen those little guys dropped from scaffold, used in sauna like environments, rain, you name it, they are tough little units, ive never seen one broken.....that being said, the whole board is encapsulated in some kind of expoxy from what i recall, and thats really all that is inside the case, so unless its just a loose connection to the board repair is going to be the whole board...$$ so if your going to get it, get it cheap, like 100$ kinda cheap
i have had one of those little guys for almost 17 years, 6010 is a no go, it will burn 6011 decently, 7018 burns ok, getting it started is a little tricky and takes some practice compared to a larger machine, and can be frustrating to less experience stick welders, but it can lay a nice bead, and will run 1/8 7018 all day on 220, it has just enough duty cycle for it to never be a problem
as for running it on 110 with stick......3/32 7018 is the limit, short beads, take breaks, it will blow a 15 and even a 20a breaker in short order, if you are going to do any decent amount of welding on 110v you would probably be stuck with 3/32 6011 (as you will be probabaly down in the 50a range)
now tig on 110v, no problem, you can run it full out at 150a and it wont blow the breaker, they are great for that
